    Further Results on Combinatorial Properties of Order-Preserving Alternating Semigroups.
    (Confluence Journal of Pure and Applied Sciences. Published by Faculty of Science, Federal University Lokoja, Kogi State, Nigeria., 2018-11) Bakare, G. N.,; Makanjuola, S. O.
    Let Cn be the charts on Xn = {1,2,...,n} be the alternating semigroups, OAnc be the subsemigroups of order preserving alternating semigroups and N(S) be the set of nilpotents element of a semigroups OAnc . Let G(n;p,m) = | {aeS : h(a) = p^f(a) = m }| ,G(n;m) = | {aeS : f(a) = m }| and G(p; m) = | {aeS : h(a) = p }| . In this paper, some combinatorial properties of OAnc for two parameters G(n; p) were discuss and their nilpotent elements were also investigated.

    some combinatorial results on alternating semigroups
    (Department of Science Education, Federal University of Technology, Minna, Nigeria., 2013-08) Bakare, G. N.; Makanjuola, S. O.
    We constructed the elements of Anc alternating semigroup on n-objects. We also investigated the combinatorial properties of the idempotent and nilpotent elements.

    Some Results on Properties of Alternating Semigroups.
    (Nigerian Journal of Mathematics and Applications. Published by Mathematical Association of Nigeria., 2015) Bakare, G. N.,; Makanjuola, S. O.
    Let Cn be the symmetric inverse semigroup on Xn = {1,2,...,n}, Anc be the alternating semigroups of Xn. In this paper, we discuss some combinatorial properties in Anc and obtained some triangle of numbers for it.
