Presentation

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

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

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