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