The GL-l.u.st.\ constant and asymmetry of the Kalton-Peck twisted sum in finite dimensions
We prove that the Kalton-Peck twisted sum of -dimensional Hilbert
spaces has GL-l.u.st.\ constant of order and bounded GL constant. This
is the first concrete example which shows different explicit orders of growth
in the GL and GL-l.u.st.\ constants. We discuss also the asymmetry constants of
