My 42s, by U241325

1 Conversation


This page claims a record for 42's created from my researcher number. The claim relates to pure 42's, that is, expressions which do not involve brackets or functions. The claim is also made for expressions which may include functions, but still exclude brackets.


Subject to Revision at Any Time.
