 The successive alternations with flipping of the negative power "p"1 between directions l and m (Kasner epochs) continues by depletion of the whole part of the initial "u" until the moment at which "u" < 1.The value "u" < 1 transforms into "u" > 1 according to ; in this moment the negative power is "pl" or "pm" while "pn" becomes the lesser of two positive numbers ("pn" = "p"2).The next series of Kasner epochs then flips the negative power between directions n and l or between n and m. At an arbitrary ([[Irrational number|irrational]]) initial value of "u" this process of alternation continues unlimited.
