WebTheorem. The idea is to first note that a spanning arborescence is a spreg. We then count the spanning arborescences contained in a graph by first countingall the spregs, then use the Principle of Inclusion/Exclusion to count—and subtract away—those spregs that contain one or more cycles. 9.2 Counting spregs with determinants
