COMMENTS

Self-descriptive numbers are read in pairs of digits.

This uses a different method from A047841. Here the digits are described in any order, whereas in A047841 they must be described in increasing order.

EXAMPLE

E.g. 10153331 reads "One 0, one 5, three 3's and three 1's", which does indeed describe 10153331.
