Instead of Kitonum's f, we can use

anotherF := x-> ifelse( 0=frem(x+2, 4), undefined , x- 4*floor( (x + 2)/4 ) );

although this is a tiny change.

Is this one of answers ?

subs(B=1-d, algsubs( 1-d = B , A*(-1+d)/r^(1+d)));

A (1 - d)
- ---------
(1 + d)
r

What is your purpose in factorization?

> myEq:= (A/T)^(1/k)*(T/phi)^(beta/k):

> simplify( myEq^k, power,symbolic);

(-1 + beta)    (-beta)

A T            phi

> %^(1/k);

(-1 + beta)    (-beta) (1/k)

(A T            phi       )

The location of maplestd2e.sty depends on your OS.

If your maple is  "Maple 2015 (X86 64 LINUX)",  the location is

(The installed directory of Maple)/etc .

As for C,  is the following OK ?

LinearAlgebra[DiagonalMatrix]([Matrix(3,symbol=C,shape=symmetric),C[4,4],C[5,5],C[6,6]],shape=symmetric);

or

LinearAlgebra[DiagonalMatrix]([Matrix(3,symbol=C,shape=symmetric),op(convert(LinearAlgebra[SubVector](ArrayTools[Diagonal](Matrix(6,symbol=C,shape=symmetric)),4..6),list))],shape=symmetric);

LinearAlgebra[Transpose] () does not help you ? (This is a just irresponsible idea.)

All you need do is to write a procedure which returns
