Presentation

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

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

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