COMMENTS

This sequences uses the same rules as the Inventory sequence A342585 except here each term is described using the 'Look and Say' method of A005150. See the Examples below. Start with a(0) = 0.

EXAMPLE

a(1) = 1 and a(2) = 0 after a(0) there is 'one 0'.

a(3) = 1 and a(4) = 1, as after a(0)..a(2) there is 'one 1'.

a(5) = 0 and a(6) = 2, as after a(0)..a(4) there is 'zero 2's'. As a number with zero occurrences has appeared the count resets back to counting zeros.

a(7) = 3 and a(8) = 0, as after a(0)..a(6) there is 'three 0's'.

a(9) = 3 and a(10) = 1 as after a(0)..a(8) there is 'three 1's.

a(11) = 1 and a(12) = 2 as after a(0)..a(10) there is 'one 2'.

a(13) = 2 and a(14) = 3 as after a(0)..a(12) there is 'two 3's'.

a(15) = 0 and a(16) = 4 as after a(0)..a(14) there is 'zero 4's. As a number with zero occurrences has appeared the count resets back to counting zeros.
