As well known, stars are visible in galaxies, galaxies in clusters, and clusters in superclusters of galaxies. It is the superclusters catalogued (in our neighborhood) that are mentioned above, of which (numbered in right ascension) we pick out four following superclusters with artificial but authentic numbers, the more striking are their features.

means

The catalogue (which contains 220 members, including 86 candidates marked with c) does not go as far as the number 233, or 700/3, and misses - you almost guessed! - the number 102 (300/3, 400/4 or 700/7). The number 176, in place of 175 or 700/4 exactly, seems a miscount. Zero denotes the local supercluster (we dwell in) kept out of numbering as any one-cluster one. The four depicted are two-cluster superclusters, or cluster pairs equally, with cluster pairs forming about half of the catalogue - in order to evaluate their probability.

Distances (restricted therein to redshift 0.12) are measured in M = Mpc/h₁₀₀. The Hubble constant h₁₀₀ being equal to 0.65 (the value absent in the catalogue but set once by J. and M. Einasto) proves to be the geometric mean of 3/4 and 4/7. A natural unit turns out equal to 75 M as well as its golden section 45 M or duplication 120 M.

The round sum 96 + 58 + 125 + 81 degrees (calculate it to your surprise) does not suppose flatness. Incidentally, to divide the straight angle in 3 : 4 is to put aside the angle of 4/3 radian, with an error less 3/4 degree.

Calculate also the mean-geometric relations:
(57x133)^1/2/(75x176)^1/2 (~ 3/4) of numbers,
(201x229)^1/2/(276x305)^1/2 (under 3/4) of distances,
(58x81)^1/2/(96x125)^1/2 (= 0.62... meaning 0.618... in ideal) of angles.

For orientation three stars entered in L3xicon.com to foresee toilers' requests are pictured and for completeness a table of equatorial coordinates is appended.
