In the context of string theory, a key question is whether or not the deformations preserve Weyl invariance. Typically, the λ deformation of Z4 supercosets leads to Weyl invariant string sigma models, while this is only the case for the η deformation when the operator R is unimodular [67...
Let us first look at the possible combinations, and the number of ways to arrange each combination.Possible combinations Number of ways to arrange 1+1+1+7=10 4 1+1+2+6=10 12 1+1+3+5=10 12 1+1+4+4=10 6 1+2+2+5=10 12 1+2+3+4=10 24 2+2+2+4=10 4 2+2+3+3=10...

We searched through many combinations of possible shift distances (and rotation distances) inGimli, applying a simple security model to each combination. Large shift distances throw away many nonlinear bits and, unsurprisingly, turned out to be suboptimal. The finalGimlishift distances (2, 1, 3 on...
combination组合,表示字母为C,是无序的;从n个不痛的元素中取出m个元素并成一组,叫做从n个不同元素中取出m个元素的一个组合.表示为m Cnpermutation排列,表示字母为A,是有序的;从n个不痛的元素中取出m个元素,按照一定的顺序排成一列,叫做从n个不同元素中取出m个元素的一个排列.表示为:mAn结果...
