	OFFSET	`1,2`
	COMMENT	`a(10^n) =0 = a(10k+5),if 10k + 5 is not==0 (mod 25). Are there any other numbers r such that a(r) =0?`
	EXAMPLE	`a(14) = 0 because any number ending in 14 is even but not divisible by 4 and any even power is divisible by 4. [From David Wasserman (dwasserm(AT)earthlink.net), Jan 15 2009]`
