PGC 36122 (= UGC 6614)
A 14th-magnitude spiral galaxy (type (R)SA(r)a?) in
Leo (RA 11 39 14.9, Dec +17 08 37)
Based on a recessional velocity of 6350 km/sec, PGC 36122 is about 300 million light years away. Given that and its apparent size of 3.0 by 2.4 arcmin, it is about 260 thousand light years across. Used by the de Vaucouleurs Atlas of Galaxy Types as an example of galaxy type SA(r)a (giant LSB).

PGC 36268
A magnitude 16(?) spiral galaxy (type Sbc?) in
Ursa Minor (RA 11 40 39.0, Dec +89 05 07)
A possible companion of NGC 3172, so for anything else see here

PGC 36393
A 15th-magnitude lenticular galaxy (type SB0^+?) in
Crater (RA 11 43 09.4, Dec -12 51 51)
A possible companion of NGC 3831, so for anything else see here

PGC 36416
A 15th-magnitude spiral galaxy (type Sab) in
Crater (RA 11 43 22.4, Dec -12 53 14)
A possible companion of NGC 3831, so for anything else see here

PGC 36431
A 14th-magnitude spiral galaxy (type Sbc) in
Leo (RA 11 43 22.7, Dec +16 29 08)
Based on a recessional velocity of 6545 km/sec, PGC 36431 is about 300 million light years away. Given that and its apparent size of 2.8 by 0.35 arcmin, it is about 250 thousand light years across.

PGC 36463
A 14th-magnitude spiral galaxy (type SABc?) in
Ursa Major (RA 11 43 46.4, Dec +55 02 51)

Based on a recessional velocity of 6680 km/sec, PGC 36463 is about 310 million light years away. Given that and its apparent size of 0.7 by 0.6 arcmin, it is about 65 thousand light years across. It is a starburst galaxy.

PGC 36466
A 14th-magnitude irregular galaxy (type Im?) in
Leo (RA 11 43 49.1, Dec +19 58 06)

Based on a recessional velocity of 6725 km/sec, PGC 36466 is about 315 million light years away, in fair agreement with a single redshift-independent distance estimate of 340 million light years. (A second recessional velocity measurement of only 5970 km/sec yields a distance of only 280 million light years, but as of this writing which if any of the three distances should be used is unclear.) Aside from having a very elongated, irregular appearance, PGC 36466 has a bright, active center and is considered a starburst galaxy. Since its distance is so uncertain, the physical size corresponding to the galaxy's apparent size of 1.9 by 0.3 arcmin is unknown; but using the whole range of distances stated above, the galaxy is between 155 and 190 thousand light years across, which is very large for an irregular galaxy, and even without the starburst activity would suggest that it is the result of a galactic collision and merger which is in its latter stages.
