(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A126268 Triangle read by rows: row n gives lengths of Huffman codes with n (>= 3) symbols, where symbol[k] has frequency k (k=1,..,n), in increasing k. 2
2, 2, 1, 3, 3, 2, 1, 3, 3, 2, 2, 2, 4, 4, 3, 2, 2, 2, 4, 4, 3, 3, 3, 2, 2, 5, 5, 4, 3, 3, 3, 2, 2 (list; graph; refs; listen; history; internal format)

EXAMPLE

Possible huffman codes for n = 3,4,5 are:

1 : 00

2 : 01

3 : 1

1 : 100

2 : 101

3 : 11

4 : 0

1 : 000

2 : 001

3 : 01

4 : 10

5 : 11

so the triangle is:

row #3: 2,2,1

row #4: 3,3,2,1

row #5: 3,3,2,2,2

etc.
