Appears in sequences

• Numbers n with property that n is a substring of its base 5 representation.at n=25A038105
• Numbers k such that k is the substring identical to the most significant digits of its base-5 representation.at n=5A307256
• Triangle read by rows: T(n, k) (2 <= k <= n) is the smallest positive integer m >= k such that the digits of m expressed in base n are the same as the first digits in base k.at n=39A380293
• Triangle read by rows q(b1,b2) with 1<b1<b2 with q(b1,b2) being the least integer k equal to or greater than b1 such that all the digits of k read in base b2 are the beginning digits of k read in base b1; or 0 iff b2 is perfect power, m^k (A001597), and b1 is m^j, 0<j<k.at n=31A380564
