This SN showed unique features: the LC had two maxima, and declined rapidly after the second maximum, while the spectra showed strengthening He lines whose velocity increased with time. The double-peaked LC can be reproduced by a double-peaked $^{56}$Ni distribution, with most $^{56}$Ni at low velocity and a small amount at high velocity. The rapid post-maximum decline requires a large fraction of the $\\gamma$-rays to escape from the $^{56}$Ni-dominated region, possibly because of low-density ","authors_text":"A. Szentgyorgyi, C.H.
