Presentation

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

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

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