Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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