Presentation

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

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

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