Just guessing... Are some of these #'s involved in Easter calculations? At 11:01 AM 7/11/2011, Alex Bellos wrote:
Hi - I've just received an email from a reader who saw in a Cologne museum a document called Fundamentalis Tabula Arithmetica from 1638. It is a table of multiples for all the numbers up to 100 and also the tables for these five numbers:
106, 117, 256, 318 and 365
Its pretty obvious why 256 and 365 are included.
Might anyone have any thoughts as to why 106, 117 and 318 (3x106) are also included?
