# gismu differing in one letter only

Suppose each of 1342 gismu is represented by a dot (vertex) on a sheet of paper. Now let us connect with a line (link) those gismu which differ only in one letter. The resulting picture is a graph consisting of vertices and links. The number of links attached to a vertex varies from 0 to 10.

The statistics is the following:

#of links #of vertices 497 361 226 134 65 35 15 6 2 1 (barna)

1342

The champion is barna: 10 links

et cetera...

As a result, the totality of gismu will be split into groups (connected components) such that any two gismu within the same group can be connected by a continous line (that is one gismu can be obtained from another via a sequence of steps changing one letter at a time).

The statistics is the following:

size of group #of groups 497 90 29 14 5 4 1 1 4 1 1 1 1 1 1

1342 gismu 651 group

Curiously, on the map of the gismu space there are 2 huge continents (161 and 131 gismu), 3 smaller subcontinents (60, 33, 26) and an archipelago of smaller islands (sizes from 11 to 1 gismu).

Here is the list of the biggest cluster (161 gismu):

The gismu are given above in no particular order. The proper representaion would be a graphic one (vertices and links) but it needs a lot of handwork.

For any pair of gismu belonging to the same connected components we can introduce a distance as the minimal number of links connecting them. The maximal distance between two gismu turns out to be 27. There are only 4 chains of the length 27:

• cunmi-...-lacri
• cunmi-...-vacri
• farvi-...-lacri
• farvi-...-vacri

The 4 chains are basically variants of the same sequence starting with cunmi-curmi- or farvi-carvi, continuing as
