Resumen de Boundaries in higher dimensions and their kinship with combinatorics

Kate Nowak, J. Kevin Colligan (ed. lit.), Maria G. Fung (ed. lit.), Dan Kalman (ed. lit.), Jeffrey J. Wanko (ed. lit.)

• A description of a collaborative investigation by mathematics teachers into the numbers of dimensional boundaries for n > 2. Functions are fit to the patterns observed, and a relationship to Pascal's triangle is noted.
