• Numbers n with property that n is a substring of its base 5 representation.at n=17A038105
• Number of compositions of n with first part 4 and no equal adjacent parts; this is column 4 of the array in A096568.at n=23A096572
• Consider a number n with m decimal digits. The sequence lists the numbers n having the suffix of length m-1 in the middle of the decimal expansion of n^2.at n=37A242964
• "Inside numbers". Pick a term "t" and one of its digits "d". Now jump to the right over d digits if "d" is odd, and to the left over d digits if "d" is even. Whatever the "d" you choose, you will stay on "t".at n=22A284515
• Consecutive states of the linear congruential pseudo-random number generator 170*s mod 30323 when started at s=1.at n=22A385033
• Smallest even number which cannot be written as the difference of two numbers which are less than and relatively prime to (the primorial) p(n)#.at n=4A389506
