| Notes: | This interesting field contains two peculiar galaxies; NGC 3718 ( a
large Arp galaxy),
NGC 3729 (3.0' x
2.2', 11.4 mag, SB(r)a pec), and a Hickson galaxy group (Hickson
56). The Hickson 56 group is the little string of galaxies South
(below) of
NGC 3718. It consists of five small galaxies, the middle three which
appear to be in contact and interacting. See
