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