As {{mvar|k}} becomes larger, the ratio {{math|{{sfrac|''t<sub>k</sub>''|''s<sub>k</sub>''}}}} approaches [[square root of 2|{{sqrt|2}}]] ≈&nbsp;{{val|1.41421356}}, and the ratio of successive square triangular numbers approaches {{nowrap|(1 + {{sqrt|2}})<sup>4</sup>}} {{nowrap|{{=}} 17 + 12{{sqrt|2}}}} ≈&nbsp;{{val|33.970562748}}. The table below shows values of {{mvar|k}} between 0 and 1114, which comprehend all square triangular numbers up to {{val||e=1621}}.
