The Royal Statistical Society have announced ‘Show me the data’ events at the Conservative and Labour party conferences this autumn. Each conference will host three meetings relating to “the importance of interpreting and understanding statistics”, run by the RSS with the Alliance for Useful Evidence and Ipsos Mori.

- From Bracket 3: A001462, Golomb’s sequence.
- From Bracket 4: A023811, the largest metadromes in base $n$.
- From the first round of reviews, we picked the one whose score we fiddled the least: A010727, all the 7s.
- And the wildcard is A058883, the wild numbers.
Solids of Constant Width now available from Maths Gear
If you like your shapes to be of constant width, friends of the Aperiodical Matt Parker and Steve Mould, who run Maths Gear, have long been the market leader in selling you flat 2D shapes which have the same diameter no matter which direction you measure in (well, them and the Royal Mint). But if you prefer your shapes to be of constant width in three dimensions, you can now satisfy those urges too at MathsGear.co.uk.
They’ve just launched a new product, which is a handsome set of yellow solids of constant width (for those interested, they’re not the standard Reuleaux triangle-based solid of revolution commonly sold – they’re Meissner Tetrahedra). A set of three, which allows you to test the constant width property by rolling them between a table and a book, is yours for £15, with free delivery in the UK. Tables and books sold separately.

Not Mentioned on the Aperiodical this month, 21 August
Here are three things we noticed this month which didn’t get a proper write-up, due to thesis/Edinburgh fringe/holidays: a big proof, a fun maths book club, and a ridiculous bit of pi-related madhattery.
Integer Sequence Review Mêlée Hyper-Battle DX 2000, THE GRAND FINALE
Welcome to the Field of Dreams. Talking of which: why can’t you grow wheat in $\mathbb{Z}/6\mathbb{Z}$?
Anyway, we’re finally here: the Grand Finale of our tournament to find the Integest Sequence 2013. Here’s a reminder of the sequences vying for the title:
It’s a been a long, hard battle. We’ve seen some good sequences, some bad sequences, and an awful lot of plagiarised GIFs. So, without further ado, it’s time to start the
Maths at the Fringe
Starting next week, the historic city of Edinburgh will be taken over by entertainers of all types, performing comedy, dance, theatre and music, entertaining visitors to their massive world-famous festival fringe. Since discerning mathematicians sometimes also enjoy being entertained, I thought I’d write a roundup of the shows maths has non-empty intersection with.
First up, since we haven’t mentioned him in a while, it’s Alan Turing! No, his reanimated corpse isn’t performing edgy stand-up, but theatre company Idle Motion is performing a visual theatre piece entitled That Is All You Need To Know, celebrating the work of Bletchley Park codebreakers. Alan Turing Alan Turing Alan Turing.
Enormous Sierpiński tetrahedron made of balloons
A group called Pyraloons set themselves the challenge of building the world’s biggest Sierpiński tetrahedron from balloons. And they succeeded! I’ll let the pictures speak for themselves:
