Dear seqfans,
My 'combination sequence number' uniquely
and easily numbers and counts any
combinations of 6x lotto numbers in all Lottos.
6/40, 6/49, 6/52 CHOOSE 6 lucky numbers from 1 to 40
WITHOUT REPLACEMENT.whatever.
It could be applied to an oeis SEQuence that contained
terms e.g. 5 10 15 20 25 30.
(e.g. closest lottery combinations = combination sequence number
has small difference. rec.gambling.lottery)
Example Below.
Myprog 'SeriCalc4S' calculates continued fraction convergents.
Example below.
'What is 10-millionth rational in McDonald scheme?' (sci.math)
Simply and uniquely calculates 1-1 map rationals onto natural nos.
Q -> Z+.
