Appears in sequences

• Numbers n such that all the divisors of n appear as substrings in n^3.at n=19A074493
• Least m ending in 1 such that m^n ends in a string of n 0's followed by the final 1.at n=7A085610
• n is prime and digits of n^3 include digits of n as substring.at n=16A115739
• Primes p such that p^s ends with p, where s is sum of the digits of p.at n=19A171267
• Smallest number m > 1 such that m^2 == 1 (mod 10^n).at n=8A181539
• (2*16^(5^n) - 1) mod 10^n: a sequence of trimorphic numbers ending in 1.at n=7A224474
• (2*16^(5^n) + (10^n)/2 - 1) mod 10^n: a sequence of trimorphic numbers ending (for n > 1) in 1.at n=8A224476
• Primes p such that the decimal expansion of p^5 ends in p.at n=37A224904
• Smallest prime numbers characterized by a convergence speed of n, assuming a(1) = 2 (since 2^2 <> 2^2^2 (mod 10) and 2^2^2 == 2^2^2^2 (mod 10)).at n=7A339313
