Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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