Presentation

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

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

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