“…In one of the computer experiments [11] using a designed program of binary matrices multiplication with classic and non-classic substitutions ( Figure 3) numerical set of 34 number values made a substitution set consisting of 91 BSG operations. Out of the set, two operations subgroups can be highlighted (including g[0]), which create small finite subsets (Table 2) visualization of three operations, randomly chosen from Table 1, is presented in Figure 2 [15]. [1], g [8] Table 1 in one dimensional space (а) and g[0], g [1], g [8] in two-dimensional space (b).…”
