The -tadpole graph, also called a dragon
 graph (Truszczyński 1984) or kite graph (Kim and Park 2006), is the graph obtained
 by joining a cycle graph 
 to a path graph 
 with a bridge.
The -tadpole graph is sometimes known
 as the 
-pan graph. The particular cases of the 
- and 
-tadpole graphs are also known as the paw
 graph and banner graph, respectively (ISGCI).
Precomputed properties of tadpole graphs are available in the Wolfram Language as GraphData["Tadpole", 
m, n
].
Koh et al. (1980) showed that -tadpole graphs are graceful
 for 
,
 1, or 3 (mod 4) and conjectured that all tadpole graphs are graceful
 (Gallian 2018). Guo (1994) apparently completed the proof by filling in the missing
 case in the process of showing that tadpoles are graceful when 
 or 2 (mod 4) (Gallian 2018).
