COMMENTS
|
This version ignores the offset of A_n and just counts from the beginning of the terms shown in the OEIS entry.
Thus a(8) = 6 because A_8 begins 1,1,2,2,3,4,5,6,... [even though A_8(8) is really 7].

a(43) is presently unknown, since A000043(43) is the exponent of the 43rd Mersenne prime. a(44) = 413927966. - N. J. A. Sloane, May 25 2005
Corrected a(26), a(36) and a(42). - M. F. Hasler, Jan 30 2009
