What package macro \isp comes from? As I understood, there is not way not get such infomation quick, reliable way. I hope I am wrong.

EDIT: My problem is that I have legacy code, that used a very ancient versions of everything. Now I have a take to build it on moder LaTeX environment. It looks like inverted by vertical \Phi.

Do you have such a LaTeX document that contains this command? If so, remove all from it except the \isp command, try removing the package imports one by one, until the \isp gives an error as being undefined. – Alexis Pigeon May 26 '12 at 10:36

Anybody is allowed to define macros with any name. Try and make the question more precise, please. – egreg May 26 '12 at 10:37
Well, \Phi is symmetrical both in the horizontal and in the vertical directions. Is it \Omega, perhaps? – egreg May 26 '12 at 10:54
Looking at the name and the description you gave, perhaps it's an inverted psi? Something like \usepackage{graphicx} \newcommand\isp{\rotatebox{180}{$\psi$}}? – Gonzalo Medina May 26 '12 at 14:00
