Partial geometry

An incidence structure $C=(P,L,I)$ consists of points $P$ , lines $L$ , and flags $I \subseteq P \times L$ where a point $p$ is said to be incident with a line $l$ if $(p,l) \in I$ . It is a (finite) partial geometry if there are integers $s,t,\alpha\geq 1$ such that:

A partial geometry with these parameters is denoted by $pg(s,t,\alpha)$ .
