I'm currently studying (theoretical) mathematics. I'm very much interested in (algebraic & geometric) topology and abstract algebra, but discrete mathematics is also nice.

Favourite books: Grillet Abstract Algebra, Weibel Homological Algebra, Davis Kirk Algebraic Topology, Greuel Pfister A Singular Introduction to Commutative Algebra, Michor Differential Geometry, Loday Cyclic Homology, Gortz Wedhorn Algebraic Geometry 1, Bondy Murty Graph Theory, Tauvel Yu Lie Algebras and Algebraic Groups, Klenke Probability Theory.

comment triangle like \textcorner
Now it works perfectly in superscript. Just two more requests. Why must I use M_n^{\triangleu} instead of M_n^\triangleu? Why are both symbols in M_n^{\triangleu}\triangleu of the same size?

Applying \reflectbox provides a way too enlarged symbol. Also, the triangle is positioned too high (overlapping with the text from the line above).

None of the packages I already have suffice for this? At this rate, each new symbol I incorporate requires a new package. Also, why doesn't \newcommand{\utriangle}{\text{\linethickness{.1ex}\setlength{\unitlength}{.8ex} \begin{picture}(1,1)(0,-1) \polygon(0,1)(1,0)(1,1) \end{picture}}} suffice?

I'd like to incorporate this into my large Texy file, which already has a lot of packages, which I've included in the opening post. Is adding pict2e really necessary? And why do you need two commands?
