[seqfan] extending A179192 (periods of 1/n)

A179192 ( n: gcd(n,10) >1 and the period of 1/n in decimal representation a prime)
seems to be dropping 45: 1/45 = 0.022222... and 2 is prime.
Basically this means that the current union A179192 U A175545 is not
A061564. Can someone provide an improved version of A179192?
