By defining subgroupoids and ideals of a groupoid with Sheffer stroke, it is proved that every ideal of a groupoid with Sheffer stroke is a subgroupoid but the converse is generally not true. Also, a congruence relation is described on the groupoid by means of ideals, and a quotient groupoid with Sheffer stroke is constructed via this congruence. Finally, relationships between Sheffer stroke algebras and this groupoid are presented.eninfo:eu-repo/semantics/closedAccessGroupoidSheffer StrokeIdealCongruenceArticle10.1142/S17935571255005972-s2.0-105009499544
