Here is a proposal.



documentclass{article} 
usepackage{tikz-cd}
begin{document}
begin{tikzcd}
A arrow[r,"b"] arrow[d,"g"] & C arrow[r,"alpha"] arrow[d,"gamma",pos=0.4,swap]& D arrow[d,"beta"]\
B arrow[rru,"h",pos=0.7,swap] & B' arrow[r,"omega"] & D'
end{tikzcd}
end{document}


enter image description here



I added the proposal to prove that users are willing to help. However, the purpose of this site is not to get screen shots converted to LaTeX code. Rather, the idea is that you try something, and if you get stuck, you have a code that you can show and others will help you solve that problem.

    My code is only "basic".



    enter image description here



    documentclass{standalone}
    usepackage{tikz-cd}
    begin{document}
    begin{tikzcd}
    A arrow[r, "f"] arrow[d, "g"'] & B arrow[r, "alpha"] arrow[d, "h"'] & D arrow[d, "beta"] \

      Another possibility is with pstricks– more precisely the psmatrix environment:



      documentclass[border=8pt]{standalone}

      usepackage{pst-node, auto-pst-pdf}

      begin{document}

      $ begin{psmatrix}[colsep =1.2cm, rowsep=1.2cm, nodesepA=2pt, nodesepB=1pt, shortput=nab, labelsep=1pt, arrows=->, arrowinset=0.12, linewidth=0.6pt]
      A & B & D \
      C & B' & D'
      %% horizontal maps
      ncline{1,1}{1,2}^{b}
      ncline{1,2}{1,3}^{alpha}
      ncline{2,2}{2,3}_{lambda}
      %% oblique map
      ncline{2,1}{1,3}naput[npos=0.7]{h}
      %% vertical maps
      ncline{1,1}{2,1}<{g}
      ncline[border=1pt]{1,2}{2,2}nbput[npos=0.35]{gamma}
      ncline{1,3}{2,3} >{beta}
      end{psmatrix} $

        I added the proposal to prove that users are willing to help. However, the purpose of this site is not to get screen shots converted to LaTeX code.
