What is the order of the Pancake graph in Given example & what are the properties of Pancake graph? [closed]

Question

Pancake graph have least diameter & degree (log n/ log log n)

pancake Graph with order-2 will be one single line with two nodes, labeled with permutation of node {12, 21}.

pancake Graph with order-3 will be one single line with one hexagonal, labeled with permutation of node {123, 132, 213, 231, 312, 321}.

Similarly for order-4 graph will be with 4-hexagonal.

This graph is in three dimension or four dimension? if this graph is in four dimension, then how graph will look like in three dimension?
