Periodicity of the last digits of some combinatorial sequences
Journal of integer sequences, Tome 17 (2014) no. 1
In 1962 O. A. Gross proved that the last digits of the Fubini numbers (or surjective numbers) have a simple periodicity property. We extend this result to a wider class of combinatorial numbers coming from restricted set partitions.
