According to Wikipedia:

Ta ⁡ ( 2 ) = 1729 = 1 3 + 12 3 = 9 3 + 10 3 {\displaystyle {\begin{aligned}\operatorname {Ta} (2)=1729&=1^{3}+12^{3}\\&=9^{3}+10^{3}\end{aligned}}}

Ta ⁡ ( 3 ) = 87539319 = 167 3 + 436 3 = 228 3 + 423 3 = 255 3 + 414 3 {\displaystyle {\begin{aligned}\operatorname {Ta} (3)=87539319&=167^{3}+436^{3}\\&=228^{3}+423^{3}\\&=255^{3}+414^{3}\end{aligned}}}

Ta ⁡ ( 4 ) = 6963472309248 = 2421 3 + 19083 3 = 5436 3 + 18948 3 = 10200 3 + 18072 3 = 13322 3 + 16630 3 {\displaystyle {\begin{aligned}\operatorname {Ta} (4)=6963472309248&=2421^{3}+19083^{3}\\&=5436^{3}+18948^{3}\\&=10200^{3}+18072^{3}\\&=13322^{3}+16630^{3}\end{aligned}}}

Ta ⁡ ( 5 ) = 48988659276962496 = 38787 3 + 365757 3 = 107839 3 + 362753 3 = 205292 3 + 342952 3 = 221424 3 + 336588 3 = 231518 3 + 331954 3 {\displaystyle {\begin{aligned}\operatorname {Ta} (5)=48988659276962496&=38787^{3}+365757^{3}\\&=107839^{3}+362753^{3}\\&=205292^{3}+342952^{3}\\&=221424^{3}+336588^{3}\\&=231518^{3}+331954^{3}\end{aligned}}}

Ta ⁡ ( 6 ) = 24153319581254312065344 = 582162 3 + 28906206 3 = 3064173 3 + 28894803 3 = 8519281 3 + 28657487 3 = 16218068 3 + 27093208 3 = 17492496 3 + 26590452 3 = 18289922 3 + 26224366 3 {\displaystyle {\begin{aligned}\operatorname {Ta} (6)=24153319581254312065344&=582162^{3}+28906206^{3}\\&=3064173^{3}+28894803^{3}\\&=8519281^{3}+28657487^{3}\\&=16218068^{3}+27093208^{3}\\&=17492496^{3}+26590452^{3}\\&=18289922^{3}+26224366^{3}\end{aligned}}}
