Again, the p-otenuse has one right corner at the origin of the posiive orthant, and the rest of them must be "p-acute" -- defined by requiring that each dihedral angle at the corner is acute.
but should have worded the last sentence as: << Again the p-otenuse has one right corner at the origin of the positive orthant, and the rest of them must be "p-acute" -- defined by requiring that each angle between two edges emanating from this corner is acute.
