Abstract: Euler's pentagonal number theorem was a spectacular achievement at the time of its discovery, and is still considered to be a beautiful result in number theory and combinatorics. In this paper, we obtain three new finite generalizations of Euler's pentagonal number theorem.

Keywords: \$q\$-binomial coefficient; \$q\$-binomial theorem; pentagonal number theorem
