Presentation

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

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

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