Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2,4,3)(6,7)(8,9)(11,12)(14,18)(15,21)(16,23)(19,26)(20,25)(24,27);(1,3,4,2)(5,6,9,11,10,12,8,7)(13,14,16,18,17,20,23,25)(15,19,22,24,21,27,28,26);(5,7,8,12,10,11,9,6)(13,15,16,22,17,21,23,28)(14,19,18,24,20,27,25,26);(5,8,10,9)(6,7,12,11)
