Presentation

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

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

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