Re: the notion of relativity of simultaneity

 'Hyperplane' has a sigtly different meaning than 'hyperplane of present time'.
 But apparently your question was about the 'hyperplane of the present' in context of RT and not about the general case of a hyperplane in mathematics.
 In case of RT, my explanation was correct!

The two notions are similar.
"Hyperplane of present time" and "hyperplane of simultaneity" are synonymous (whatever the theory used, Newton, Einstein, Hachel).
