Lunar squares n that can be written as n = i·i in more than one way. A180513
Smallest n-digit member of A089699. A89700
a(n) is the least positive integer in base 10 containing n ones that is divisible by n. A112891
A base-3/2 sorted Fibonacci sequence that starts with a(0) = 0 and a(1) = 1. The terms are interpreted as numbers written in base 3/2. To get a(n+2), add a(n) and a(n+1), write the result in base 3/2 and sort the "digits" into increasing order, omitting all zeros. A305753
a(1) = 1, then the smallest number not included earlier and not a string of 1's such that the concatenation a(n), a(n+1) is a palindrome. A83122
A Jacobsthal sequence (A078008) to base 4. A92900
Composite numbers whose product of digits is 2. A201015
