Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

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