From OeisWiki

The number set of nonnegative integers consists of the union of the zero element with the set of positive integers.

The sequence of nonnegative integers is (A001477)

- {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, ...}

In the OEIS, sequence entries known or believed to consist entirely of nonnegative integers are given `keyword:nonn` (Category:Keyword nonn).
