(n, 1, 2, \dots, n-2, n - 1)st conversion.
Permutes the terbri so that the mth sumti slot of the new selbri is the (m-1)st sumti of the original selbri, for any natural m such that 1 < m \leq n, and the first sumti of the new selbri is the last (id est: nth) sumti slot of the original selbri, where the cardinalities of the terbri of the original (and thus new) selbri each are n (such that n is a natural number). This permutation is given by the cycle (n, 1, 2, \dots, n-2, n-1) acting on the indices of the terbri (notice that this is cyclic permutation notation, not an ordered tuple (as appears in the definition)). For a selbri with 2 sumti slots, this is equivalent to "se"; for one with 3 slots, it is "to'ai"; for 4, it is "vo'ai"; for 5, it is "xo'ai". See also: "se'au'e" for the inverse. The behavior of this word when applied to open-ended terbri structures (such as for "jutsi") is yet to be explored; use it cautiously in such contexts, or perhaps not at all.
