Presentation

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

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

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