Recent progress on theoretical predictions of ternary superhydrides and theirsubsequent experimental confirmations have introduced us with a new generationof superconductors, having the potential to realize the synthesis of the mostanticipated room temperature superconductors. Motivated by the recent highpressure experiment on YH$_6$ and EuH$_6$, we have theoretically examined thestability as well as superconductivity by mixing the two compounds. Here weidentified four phases capable of maintaining thermodynamic stability in thepressure range of 150-300 GPa, namely $Fm\bar{3}m$-Y$_{3}$EuH$_{24}$,$Cmmm$-YEuH$_{12}$, $Cmmm$-YEu$_{3}$H$_{24}$,$Immm$-YEu$_{3}$H$_{24}$. Amongthem, only $Fm\bar{3}m$-Y$_{3}$EuH$_{24}$ can maintain dynamically stability inthe searched pressure range. The Allen-Dynes modified McMillan formula was usedto further check the superconductivity of this phase, and the results revealthat the predicted superconducting transition temperature $T\rm_{c}$ ofY$_{3}$EuH$_{24}$ is approaching 220 K at 200 GPa.$Fm\bar{3}m$-Y$_{3}$EuH$_{24}$ has a nearly identical logarithmic averagephonon frequency $\omega_{log}$ to YH$_{6}$, but its electron-phonon coupling(EPC) constant $\lambda$ is somewhat smaller than YH$_{6}$'s 2.56, resulting ina lower ultimate $T_{c}$ value.
