OEIS Sequences

Smallest multiple of n beginning with n and having a digit sum n, or 0 if no such number exists. A77727

Numbers k for which φ(A267099(k)) is equal to φ(k), but the number of 4m+1 and 4m+3 primes in the prime factorization of k (when counted with multiplicity) is not equal. Here A267099 is fully multiplicative involution swapping the positions of 4m+1 and 4m+3 primes, and φ is Euler totient function. A354194
