COMMENT

a(n) = A014963(n)^A100995(n) = n^A010055(n);

a(A000961(n)) = A000961(n).

a(n) is the smallest positive integer such that n divides LCM(a(1),a(2),a(3),...a(n)), for all positive integers n. - Leroy Quet May 01 2007

a(1) = 1 is ambiguous: it could be 1 because 1 is a prime power p^0 for any prime p (if 0 is admitted as exponent) or it could be 1 because 1 is not a prime power (if 0 is not admitted as exponent.) [From Daniel Forgues (squid(AT)zensearch.com), Aug 18 2009]
