I'm trying to define a Vandermonde matrix (https://en.wikipedia.org/wi...) in CAS:
Sequence(Sequence(i^j, j, 0, 9), i, 1, 10)
CAS expands i^j so, for instance, 2^3 is expanded to 8. I would like to keep the format 2^3.
I tried a matrix of texts instead:
Sequence(Sequence(Text[i + "^" + j], j, 0, 9), i, 1, 10)
But this command returns an array of "?".
How to generate a Vandermonde matrix (numerical or as text) keeping the power layout?

Oh, thank you!
