Remember that
primes = A40, partitions = A41
and has been that way for ever
Reason:
A40 2 3 5 7 11 13 ...
comes before
A41 [1 1] 2 3 5 7 11 15 ...
in lexicographic order, which was adopted by me in the mid 1960s
A43 is 2, 3, 5, 7, 13, 17, 19, 31 .. 2^n-1 is a prime (Mersenne
exponents)
The common beginning of 2 3 5 7 ... is what led Richard Guy to write his
famous paper "the strong law of small numbers"
This question came up because there are still sequences that say p(n) in
their definition - it is recommended that you say either prime(n) or
partition(n)
