Gleaming the Cube who gets kids to try an incredibly hard trick called the "Monster Cookie Pinwheel". When asked by the skaters what a Monster Cookie Pinwheel is, Skater McGee replies with, "A monster cookie pinwheel is when you skate up to a locomotives cow catch, you 360 punk buster to the second car, do a lemonade hand stand on the third car, a whipping-post ollie to the fourth car, a demon stomper on the fifth car, and a gleaming the cube off the sixth car, before dismounting the train." A reference to "gleaming the cube" was also made in season 3 of
Principal root of unity Principal root of unity In mathematics, a principal "n"-th root of unity (where "n" is a positive integer) of a ring is an element formula_1 satisfying the equations In an integral domain, every primitive "n"-th root of unity is also a principal formula_3-th root of unity. In any ring, if formula_3 is a power of formula_5, then any formula_6-th root of formula_7 is a principal formula_3-th root of unity. A non-example is formula_9 in the ring of integers modulo formula_10; while formula_11 and thus formula_9 is a cube root of unity, formula_13 meaning that it is not a "principal" cube
