A101316 Sequence starts with 1 odd digit, 2 even digits, 2 odd digits, 1 even digit, then 3 odd, 2 even, 3 odd, 3 even, 3 odd, 4 even, 4 odd, 1 even, etc., where these digits are determined by the sequence itself, and the parity alternates. Always group the digits to give the slowest rate of growth subject to a(n-1) < a(n).

1, 2, 21, 32, 33, 34, 41, 51, 62, 63, 71, 82, 84, 91, 93, 211, 311, 411, 511, 522, 531, 533, 622, 711, 713, 721, 731, 733, 742, 751, 753, 754, 822, 911, 913, 915, 2111, 3111, 3122, 4112
