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