Numbers k that, when expressed in base 7 and then interpreted in base 10, give a multiple of k. A62944

Primes that yield a different prime when rotated by 180 degrees. A48890

Primes of the form 2·p-1 where p is prime and p-1 is squarefree. A153207

Numbers that, when expressed in base 7 and then interpreted in base 10, yield a multiple of the original number. A32549

A variation on Flavius's sieve (A000960): Start with the primes; at the k-th sieving step, remove every (k+1)-st term of the sequence remaining after the (k-1)-st sieving step; iterate. A99207
