It means the order in which you serialise a multi-dimensional array. So for this 2D table: 1262 3418 9076 Because it’s 2D it has two stride orders

It means the order in which you serialise a multi-dimensional array. So for this 2D table: 1262 3418 9076 Because it’s 2D it has two stride orders, xy and yx, i.e. row-major and column-major, which would be 126234189076 and 139240617286 respectively.
