Abstract

The introduction of bars in-between blocks of an ordered set partition(preferential arrangement) results in a barred ordered set partition(barred preferential arrange- ment). Having the restriction that some blocks of barred preferential arrangements to have a maximum of one block results in restricted barred preferential arrange- ments. In this study we establish relations between number of restricted barred preferential arrangements, multi-poly-Bernoulli numbers and numbers related to multi-poly-Bernoulli numbers. We prove a periodicity property satisfied by multi- poly-Bernoulli numbers having negative index, number of restricted barred prefer- ential arrangements and numbers related to multi-poly-Bernoulli numbers having negative index.
