Interesting Esoterica Summation, volume 7
Do you ever collect too much fun maths stuff to keep to yourself, and then start a website just so you’ve got somewhere to put it? That happens to me sometimes. In case you’re new to this: every now and then I encounter a paper or a book or an article that grabs my interest but…
Cushing your luck: properties of randomly chosen numbers
Long-time Aperiodical muse David Cushing has made a bet with us that he can give us an interesting post every Friday for the next ten weeks. Every week that he sends a post, we buy him a bar of chocolate. Every week that he doesn’t send us a post, he buys us a bar of…
Scrooge McDuck in Mathmagic land
A sympathetic story for you this Saturday. Andy has a problem. He can’t solve it on his own – he needs your help. This problem vexed Andy so much that he spent four years trying to solve it on his own, to no avail. It really is a very difficult problem. Finally in 1997, out…

Integer Sequence Review: A052486

The Online Encyclopedia of Integer Sequences contains over 200,000 sequences. It contains classics, curios, thousands of derivatives entered purely for completeness’s sake, short sequences whose completion would be a huge mathematical achievement, and some entries which are just downright silly. For a lark, David and I have decided to review some of the Encyclopedia’s sequences.…
