Appears in sequences
- Numbers in which each digit is the (immediate) successor of the previous one (if it exists) and 0 is considered the successor of 9.at n=49A059043
- a(n) = (10^n-1)*(91/81)-n*10^n/9.at n=5A064616
- a(n) = Sum_{ k = 0 to n-1} ( subtract k modulo 9 from 9, multiply this by k-th power of 10 ).at n=5A133486
