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