Presentation

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

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

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