Sequence Fanatics,
A062090 is a(1) = 1, a(n)= smallest odd number which does not
divide the product of all previous terms.
A050150 is Odd numbers with prime number of divisors.
They both begin: 3, 5, 7, 9, 11, 13, 17, 19, 23, 25, 29, 31, 37,
41, 43, 47, 49, 53, 59, 61, 67, 71, 73, 79,
81, 83, 89, 97, 101, 103, 107, 109, ..., .
In the comments section of A050150 it says that "This sequence
differs from A062090 by one term, "81", so far." I do not know who said
this nor do I care, but it is wrong. The two sequences match except for
the initial 1 which is needed to begin A062090 up to 729. It appears in
A050150 but not in A062090. Then 6561 appears in A062090 but not in
A050150. I'll push this further. Any comments?
Sincerely,
Robert G. "Bob" Wilson, v
