The date [day,week,month,year] x1=d1=k1 is recurrence/repetition of the date [day,week,month,year] of the first event x2=d2, for the x3=k3'rd time, in system x3.
x1 (plural of ordered pairs) is an exhaustive set (possibly infinite) of inputs/outputs defining a unary function which yields result x3 when given input x2; x1(x2) = x3
x1 (group of entity) compete with each other in competition x2 (property of each member of x1) where each member of x1 has goal x3 (property of member of x1) that is the same for all members of x1
x1 and x2 are path-linked by directed binary predicate x3 (ka) via intermediate steps x4 (ordered list; ce'o) in graph x5, such that (in the graph x5) both (A) no other node exists to which x2 is connected in/by the same way/direction/relation and (B) no other node exists to which x1 is connected in/by the opposite/(anti)symmetric/reversed way/direction/relation.
